wait time visa checks in-europe flight?

There are no passport/visa checks between Schengen countries. It's like traveling between US states.

What kind of visa do anticipate having?

The answer is no. Once you are in the Schengen it is like flying from Florida to California.

I feel most comfortable arriving at least 90 minutes early. You will have to go through security in Italy, but not immigration. In Budapest you not have to got through Immigration or Customs. Since you are carry on only you just walk through luggage claim and out the back doors, across the hall and out the doors to the sidewalk where you will find the kiosk for the taxi company.

Once you are off the plane in Budapest it will take you about 40 minutes (add 10 for rush hour) to reach your hotel (if by taxi) if it is in Pest. 10 to 15 minutes longer if your hotel is in Buda. Cost is 8.000 to 12.000 forints depending on where your hotel is and the traffic.

OR

Take the 100E bus for 2.200 forints. It stops at Kálvin tér and Deák Ferenc tér in Pest where you can get on a tram or the metro or walk. Travel time maybe 5 minutes more and maybe a 10 minute wait for the bus. If you are in Buda it gets a bit more complicated.

OR

The shuttles, but never done that. Longer wait and you get dropped off at your hotel, but your hotel could be the first or the last drop so could be a little longer or a lot longer.

IF

You are going to be using the metro a lot, then get the BudapestGo app or if you are like me and prefer paper there is a counter in the arrivals hall (look left) that sells the TravelCards.

AND (since I am on a roll)

Dont know about a RS Lite bag, but not all of RS carry on luggage meets the size requirements of all the airlines. Especially if yoiu are flying Wizz or Ryan (which do go to Italy from Budapest). So check.

AND (again)

The busiest month for tourism in Budapest is August; speciically the fisrt two weeks of August. One advantage to Budapest during the rush is that there really isnt a central tourism district (like Old Town in Prague); The most touristed zones are District 5 , District 6, and the lower half of District 7 which combined is a very large area where the tourists are widely dispersed; and every bit of it is worth seeing. Oh, also District 1 wich is Buda and which can be a bit of a mess, but thats a half day visit for most people.

You got me curious so I looked. The historic center of Rome is about the same size as Budapest combined districts I, V, VI and VII but Rome has a little more than twice the tourist numbers.

Note that even though there are no immigration checks between Schengen Area countries, there are sometimes still "conformity checkes" at the gate. These just check that the person flying is indeed the person booked to fly, and depend on the airline and the country the airport is in. Low Cost airlines typically always do this, but LH group airlines only do this when local regulations demand it.

This is not a visa/immigration check. All they do is look at the name on the passport/ID you show and see if it matches the ticket.

We should note that a country in Schengen can throw up an unexpected passport check if it wants to. That happened to me in Stockholm after a flight from Athens.

But it's very rare.

It's rare, but it does happen. And you're still crossing an international border so you have to have a passport with you.

Frank II, i have heard of it happening, but in probably 100 border crossings I have been lucky so far. But the OP isnt changing planes just going to one airport from town and then arriving at another airport. As long as they show up at the departure airport 90 to 120 minutes early should be no issue either way. And on arrival, so it takes a while longer to get in your Taxi (or what ever).

As for carrying your passport, its the law even in-country; at least in Hungary.

...and you will get your passport checked going through security to get into the secure zone of the airport.

Showing your passport to an airline official or as ID to enter security is not immigration. Nothing gets stamped, nothing gets recorded, nothing is official.

The airline just want to make sure you have one. Security just wants to make sure it's you using the boarding card. These each take seconds.

Mr. E.....I didn't change planes when I was stopped in Stockholm. Just surprised.

I remember that during the immigrant crisis some tmyeaes back that Hungary put up some land border crossing check points.

Yes, the Hungarian government but that was years ago (2015). Plus they were only checking people who didn’t look European, so…

About five years ago I was taking the train from Austria into Italy. Near the border, Austrian border guards boarded the train. It was an old train with compartments. Three other people in the compartment. (None looked European).

The guard entered the compartment and asked for passports. He first scrutinized the passport of the man sitting across from me. He had a German passport. The he checked the passports of the other two who were traveling together. He turns to me, sees me holding a US passport, shook his head and hand saying it wasnt necessary and left the compartment.

On a ferry between Copenhagen and Oslo I was asked to show my passport upon boarding. I didn't expect it and my passport was put away in my moneybelt. I did have my passport card and showed it to him. He had never seen one. I told him you cant get it unless you have a passport. He let me on. I learned my lesson....even if traveling between Schengen countries, always have my passport available.

I was checked on the ICE train from Amsterdam to Cologne as we crossed the border into Germany several years ago. No big deal.
